Abstract
Abstract A portable feedthru device is a means of parking an energized or deenergized high voltage underground cable at an electrical apparatus to bypass such an apparatus by feeding thru to other apparatus or to test and ground the parked cable to safely work on such cable. A variable portable feedthru device is a device with a type of mounting bracket which allows the portable feedthru device to be used with any type accessory bracket. The variable portable feedthru device can be oriented in any plane to accommodate any cable position. The method of locking the variable portable feedthru device in its accessory bracket is to tighten the back plate against the accessory bracket by means of a screw to create a binding action. This will improve safety by firmly holding the portable feedthru device in its accessory bracket.
